To all whom it may) concern.- Be it known that I, HERMANN LEMP, a citizen of the United 7 county of Essex State of lvlassachusetts, have invented certain new and useful Improveof which the following is a specification.

This invention relates to the steering.

mechanism of automobiles, and especially to Y the automatieeheek which prevents the steering-wheclsfrom being deflected by a rut or other obstruction in theroad and yet permits them to be movml'freely by the driveroi' the steeringmonntegl n a closedear. The so-eitlled hydraulic checks have a p'iston liquid-tilled chamber] and provided with valvcs'to permit thellq'uid to pass from one side of the piston to the other when said pis. ton is vibrated. I I

The general type of steering-"cheek to which'this invention is applicable is shown in mypriorpatent, No. 725,457, April14,1:9 ()3. In that patent there-is disclosed a controllingiingcr inside the cheek-easing, which moves steering-linger and actuvalves in the piston which lies on the side ,toward wlnch-tlwiinger moves.

The check which forms the subject ofthe presentih vention has no controlling-linger in in unison with I n place of it I' provide the. bodyof the check moving the steering-linger. an upright plunger for actuating the rocker, which. lifts the valves from their seats. .Furthermore, the roeker armfingers, that lift the valves, are )relerabl y hold the valves closed without using springs. are positively lifted at the same time instead of only one on the advancing side of the )iston.

The valves may have springs 30 resting on them to hold themto their seats, as indicated by the' dotted lines in Fig. 6. In addition to this or in lieu thereof Imay make the fingers 28 or the balls themselves, or both, of toolsteel and magnetize one or'both, so that when at rest they will be securely held to their ing-finger 19' laterally against one of the spring-buiiers, which yields and permits the This causes one of the tappets 24 to depress the plunger, thereby lifting both valves off their seats and opening a passage for the free flow of liquid from one side of the piston to the other. This unlocks the steering-gear, so that it can be moved by the continued movement of the steering-finger. When-the latter is brought to rest, the spring-buffers restore the parts to their normal position, in which the valves are liable to throw them out of order.

closed and the steering-gear locked. It will be seen that the lever and steering-finger may be shifted angularly with reference to the piston to a considerable extent without modify-v ing the action of the rock-shaft and plunger,

since the latter coincides substantially with the axis of the hub of the piston. This provides for displacement due to hard bumps,-

which in other forms ofsteering-cheeks are 7 Moreover, by opening both valves positively the action is more prompt, since if only one valve is opened positively the other must be lifted by the current of liquid. If the springs are rather strong, as they ought to be to resist any 1arr1'ng of the car, the back pressure may.
